The purpose of this sample is to demonstrate how to add support for non-image file
types into DAlbum. In particular support for movies (AVI/MPG/Windows Media/QuickTime),
audio (WAV,MP3,WMA) and PDF files is added. Support for ANY file type can
be implemented by changing a few lines in ./config/customtypes.php.

Another interesting feature is custom fields (DAlbum 1.35+). Any album or image can be
assigned a set of custom parameters which are stored in the .albumdef.ini file.
These custom fields can be changed using web interface too.

This sample defines two custom fields: Width and Height for video files.
They are mandatory for QuickTime movies and optional for AVI/MPG/Windows Media.
